Hey dude nice video ! I’m also currently making a buck converter with the LMR51430 IC. I just don’t understand why you put 2 22uF capacitors before the input pin ? The schematic on the datasheet shows only one capacitor but weirdly on the layout example they also have 2 capacitors.

Two capacitors can give you a better "response" by lowering the effective ESR. If you go on to read 9.2.2.6 of the datasheet they recommend a minimum of 4.7uF and for their design they use 2x 4.7uF capacitors so as long as you meet that you should be fine. They also recommend placing a 0.1uF capacitors very close to the pin for noise filtering.
